Xcode 4.3 is now available (free) on the Mac App Store. There’s a slight difference in distribution: it’s now distributed as an installed app rather than an app installer. This allows Xcode to be updated directly from the Mac App Store just like any other MAS-installed app.

You’ll need to launch the App Store app, search for Xcode, then install. The download weighs in at about 1.5 GB. The updates, according to the MAS, are:

• New code signing workflow to support signing OS X apps with Developer ID (for the OS X 10.8 “Mountain Lion” feature – see “Gatekeeper”)
• Adds installation of command-line tools in the Downloads preference pane
• Open Developer Tool feature launches Instruments, File Merge, and other tools
• ARC Migration tool now supports conversion of both retain/release (manual memory-managed) and Garbage Collected apps
• The ever present miscellaneous “additional bug fixes and stability improvements”

Due to popular demand, I’ve added forums to the site. Registration is required to post but anyone can browse. The forums are accessible via the main site menu.

The Xcode 4.2 gold master is now available to subscribed developers and can now be used to submit iOS 5 apps to the App Store.

If you subscribed to the mailing list, please note it will be used to announce future editions of the book when they become available. My feelings won’t be hurt if you unsubscribe now.

Great news! The book is now available for preorder from a variety of sources. The print format is expected to appear in stock around the first week of September (it takes a few weeks to print and ship) but the electronic format will be here somewhat sooner.

As I said to @peca on Twitter: May it confound you slightly less than the documentation.

Great news! All work is 100% submitted, mostly indexed, and the last few chapters are going through final proofing. The book will be off to the printers sometime in the next few days.

Apple posted Xcode 4.0.2 with iOS SDK 4.3. The release appears to be centered around stability.

As you’ve no doubt heard already, Xcode 4 was released. While those with paid developer accounts can download it free from the ADC web site, those without will need to purchase the application for US $5.99 from the Mac App Store (10.6.6 required for the App Store). Xcode 4 requires Mac OS X 10.6 or above and can be installed alongside Xcode 3.
